“We are busy building out the stamping facility right now. The question is not whether the stamping press will be here. It’s going to be here well in advance of the Model 3. But the question is really how long does it take to work out the bugs in the stamping line? And how many iterations does this one have to go through to get it operating smoothly?”

This update today shows that they are more confident about bringing it to volume production on time.

They gave updates on other parts of the production process:

“Paint shop preparation has been completed and installations of our dedicated Model 3 body welding and general assembly lines are progressing well. Equipment installation is also underway for volume manufacturing of cells, modules, battery packs and drive units at Gigafactory 1. We are working closely with all Model 3 suppliers to ensure their readiness ahead of start of production.”

Tesla said that they spent $553 million in capital expenditure during the first 3 months of the year and that the money “primarily” went to the expansions for the Model 3.

Again, they didn’t want to give any guidance as to how many Model 3 they plan on producing and delivering by the end of the year beyond the goal of reaching 5,000 units per week “at some point” in 2017, but they did say that they will provide guidance on vehicle deliveries for the second half of year after they start Model 3 production in July.
